Study of lung function tests in tea garden factory workers in relation to duration of exposure to tea dust

Rumi Konwar, Archana Khanikar.


Abstract
Background: Occupational hazard is a common health problem in the world today. The tea industry is also no exception. Tea dust inhalation leads to development of many respiratory symptoms: Acute as well as chronic. Workers in the tea factory often are not aware of the ill effects of inhalation of tea dust. There is therefore a need to make them aware of their working environment and take necessary precautions to keep themselves healthy to earn their livelihood.

Aims and Objectives: The aim of the study was to assess the pulmonary function tests (PFT) in tea garden factory workers and assess the outcome of exposure duration to tea dust in them.

Materials and Methods: The study had been carried out on 210 male tea garden factory workers (cases) and 70 male field workers (control) employed in various tea gardens of Dibrugarh, in Assam. Computerized spirometer was used to evaluate PFTs. The cases were categorized into three categories (70 numbers in every category) according to their exposure duration, namely – Category 1: Exposure duration <1 year; Category 2: Exposure duration of 1–2 years; and Category 3: Exposure duration of >2 years up to 5 years. Statistical analysis was done using ANOVA.

Results: On comparing with control group values, statistically significant decline of forced vital capacity and forced expiratory volume (FEV)1 values were seen in Category 1 while highly significant decline were seen for Categories 2 and 3. Decline of FEV1% in Category 3 was highly significant. Decline of peaked expiratory flow rate values in Category 2 and Category 3 was significant.

Conclusion: Increase in exposure duration to tea dust causes a significant decline in lung functions.

Key words: Pulmonary Function Tests; Tea Factory Workers; Exposure Duration; Tea Dust
